在 gitlab-ci 期间无法在 docker 中启动 MySQL 服务

Question

I have the following .gitlab-ci taken from the example of Laravel Dusk CI :

stages:
  - build
  - test

# Variables
variables:
  MYSQL_ROOT_PASSWORD: root
  MYSQL_USER: root
  MYSQL_PASSWORD: secret
  MYSQL_DATABASE: test
  DB_HOST: mysql
  DB_CONNECTION: mysql

build:
  stage: build
  services:
     - mysql:5.7

  image: chilio/laravel-dusk-ci:stable
  script:
    - composer install --prefer-dist --no-ansi --no-interaction --no-progress --no-scripts
    # - npm install # if you need to install additional modules from your projects package.json
    # - npm run dev # if you need to run dev scripts for example laravel mix 
  cache:
      key: ${CI_COMMIT_REF_NAME}
      paths:
        # these are only examples, you should modify them according to your project, 
        # or remove cache routines entirely, if they are causing any problems on your next builds..
        # below are 2 safe ones if you use composer install and npm install in your stage script
        - vendor
        - node_modules
         # - /resources/assets/vendors  # for example if you put your vendor node-libraries there

test:
  stage: test
  cache:
    key: ${CI_COMMIT_REF_NAME}
    paths:
      - vendor
      - node_modules
    policy: pull
    
  services:
    - mysql:5.7

  image: chilio/laravel-dusk-ci:stable
  script:
    - cp .env.example .env
    # - cp phpunit.xml.ci phpunit.xml # if you are using custom config for your phpunit tests in CI
    - configure-laravel
    - start-nginx-ci-project
    - ./vendor/phpunit/phpunit/phpunit -v --coverage-text --colors --stderr
    # - phpunit -v --coverage-text --colors --stderr # if you want to use preinstalled phpunit
    - php artisan dusk --colors --debug

  artifacts:
    paths:
      - ./storage/logs # for debugging
      - ./tests/Browser/screenshots
      - ./tests/Browser/console
    expire_in: 7 days
    when: always

However, when the runner executes the job, I keep getting the following warning:

Using Docker executor with image chilio/laravel-dusk-ci:stable ...
Starting service mysql:5.7 ...

I've tried to set the runner to privileged in the config.toml :

privileged = true

To solve the Question:

mysqld: error while loading shared libraries: libpthread.so.0: cannot stat shared object: Permission denied

• Step1: update your software and kernel(maybe):

  apt-get update && apt-get upgrade

• Step2: install the docker dependency package:

  • (ubuntu/debian): apt-get install apt-transport-https ca-certificates curl gnupg2 software properties-common
  • (centos/redhat): yum-utils device-mapper-persistent-data lvm2

• Step3: reboot your server & restart your docker-ce:

  reboot

  systemctl restart docker-ce
